Can a car start without a computer box?
yes you can bypass the computer but bear in mind, depending on which car it is, you may need to replace a lot of sensors and control valves with manual devices. For one, you’ll need to a find a new way to regulate fuel & air into the fuel injection – so you’ll basically go back to how carburetors worked.
Can you drive a car with a bad computer?
Yes, you can. Of course, it depends on the failure. If the internal power supply fails, the fuel injectors won’t be commanded on, so no fuel will get to the engine. A less severe failure would be a Radio Frequency filter capacitor.
Can I bypass the ECU?
From a practical standpoint – no. The ECU may be bypassed to perform certain system tests, but it must be present for a vehicle to run. There are some aftermarket ECU replacements, generally for racing setups. These are usually marked as off road use only.
Does fuel injection require a computer?
Originally Answered: Is fuel injection possible without the vehicle having a computer to program the injectors (ie purely mechanical)? Yes. All fuel-injected engines started out that way.
What happens when your car computer goes out?
When the ECM fails completely, the vehicle is left without an engine management control, which means that it won’t start or run properly as a result. While the engine may still crank, it requires vital input from the ECM to start.
How much does an ECM cost?
The cost for the new ECM will typically be around $800, with labor around $100, bringing the average total expense for an ECM replacement to approximately $900 before taxes and fees. This can increase depending on the shop you go to or the type of car you, running as high as $2,000.
Can the ECM be tested?
Running diagnostics and testing your ECM is how you can rule out other issues and see if there is really something wrong with the engine control module itself. The first thing to do is test the ECM to see if it returns any error codes indicating a failure of a specific engine system.
What is the purpose of a computer box in a car?
The electronic control unit that is commonly referred to as the ECU or computer box is more efficient and much safer than ever. The ECU serves as the car’s brain as it makes sure that the vehicle functions optimally throughout. The ECU or computer box manages or computes various things.
Which gives more mileage carburetor or fuel injection?
The carb variant returned 48.54kmpl and 55.02kmpl in the city and highway respectively. Aside from this, fuel injection vehicles produce far fewer carbon-based emissions compared to vehicles with carburettors.

Does disconnecting car battery reset computer?
A. It depends on the car’s age and type of ECU used. On some older cars, disconnecting the battery will reset the system but in most new cars it does nothing, except potentially reset the clock and radio station presets.
